Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to an air conditioning system and a cooling tower. Background Technology

[0002] In certain locations with high levels of dust, gas, or other pollutants where electricity is not permitted, such as return air tunnels in coal mines, cooling towers require the use of water spray to drive hydraulic fans for cooling and temperature reduction.

[0003] In the existing cooling tower process, the spray water comes into contact with the outside air. The spray water often adsorbs and dissolves a large amount of dust and impurities, resulting in serious pollution of the spray water. This leads to excessive impurities in the spray water, which reduces the working efficiency of the hydraulic fan and thus reduces the overall cooling efficiency of the cooling tower. At the same time, it also affects the service life of the hydraulic fan. Summary of the Invention

[0004] This application aims to at least solve one of the technical problems existing in the prior art. To this end, embodiments of this application provide an air conditioning system and a cooling tower that can prevent impurities from entering the hydraulic fan, improve the working efficiency and service life of the hydraulic fan, and ensure the overall cooling efficiency of the cooling tower.

[0005] In a first aspect, this application provides an air conditioning system, comprising:

[0006] Heat exchanger, used for circulating the primary coolant;

[0007] A hydraulic fan is used to introduce air into the heat exchanger so that the air exchanges heat with a first coolant in the heat exchanger and discharges the air that has been heated.

[0008] A first coolant supply device is configured to input a first coolant into the inlet of the hydraulic fan to drive the hydraulic fan to rotate.

[0009] The first coolant flowing out of the outlet of the hydraulic fan is introduced into the heat exchanger.

[0010] The air conditioning system according to the first aspect of this application has at least the following beneficial effects:

[0011] The air conditioning system of this application introduces a first coolant supply device into the inlet of a hydraulic fan, using the kinetic energy of the first coolant to drive the hydraulic fan to rotate, thereby introducing high-temperature air from the environment into a heat exchanger. This allows the air to exchange heat with the first coolant flowing through the heat exchanger pipes. The first coolant in the heat exchanger absorbs heat from the air, thus cooling it. Simultaneously, by introducing the first coolant flowing out of the outlet of the hydraulic fan into the heat exchanger, the first coolant that drives the hydraulic fan can flow from the outlet of the hydraulic fan into the heat exchanger, continuously providing the heat exchanger with the first coolant for heat exchange with the air. In this way, the first coolant supply device, the hydraulic fan, and the heat exchanger form an air conditioning system capable of cooling the environment.

[0012] When the cooling tower equipped with this air conditioning system cools the mine environment, the primary coolant supply equipment can directly and continuously supply clean primary coolant to the hydraulic fan. This clean primary coolant drives the hydraulic fan to rotate continuously, replacing the traditional method of using cooling water contaminated by the mine environment to drive the hydraulic fan. This avoids dust and other impurities in the mine from entering the hydraulic fan and affecting its working efficiency, ensuring the overall cooling efficiency of the cooling tower. Simultaneously, the primary coolant output from the primary coolant supply equipment can be recycled into the heat exchanger, continuously providing the heat exchanger with primary coolant for heat exchange with the air in the mine. This process also avoids direct contact between the primary coolant and the air in the mine, preventing contamination. This not only ensures the quality of the primary coolant but also achieves its recycling, improving its utilization efficiency.

[0013] In some embodiments, the first coolant supply device is connected to the inlet of the hydraulic fan via a first pipeline, and the first pipeline is provided with a first flow regulating valve.

[0014] In some embodiments, the first coolant supply device is also connected to the inlet of the heat exchanger via a second pipeline to supply the first coolant to the heat exchanger.

[0015] In some embodiments, a second flow regulating valve is provided on the second pipeline.

[0016] In some embodiments, the outlet of the hydraulic fan is connected to the second pipeline via a third pipeline, so that the first coolant flowing out of the outlet of the hydraulic fan is introduced into the heat exchanger via the second pipeline.

[0017] In some embodiments, the outlet of the heat exchanger is connected to the first coolant supply device.

[0018] Secondly, this application provides a cooling tower that includes the air conditioning system described above.

[0019] The cooling tower according to the second aspect of this application has at least the following beneficial effects:

[0020] Because the cooling tower of this application incorporates the aforementioned air conditioning system, it also achieves the same technical effects as such an air conditioning system. Specifically, when cooling the mine environment, the cooling tower prevents dust and other impurities from entering the hydraulic fan and affecting its efficiency, thus ensuring the overall cooling efficiency of the cooling tower. Simultaneously, it prevents the first coolant from directly contacting and contaminating the air inside the mine, ensuring the quality of the first coolant. Furthermore, it enables the recycling of the first coolant, improving its utilization efficiency.

[0021] In some embodiments, the cooling tower further includes a sprayer configured to spray a second coolant onto the heat exchanger.

[0022] In some embodiments, the cooling tower further includes a second coolant supply device configured to recover a second coolant that has slid off the heat exchanger and to supply a second coolant to the sprayer.

[0023] In some embodiments, the second coolant supply device is connected to the sprayer via a fourth pipeline, and the fourth pipeline is provided with a third flow regulating valve.

For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0038] In certain locations where there is a large amount of dust, gas, or other pollutants that prohibit the use of electricity, such as return air tunnels in coal mines, electrical equipment cannot be used due to the presence of flammable or explosive gases or substances in the environment.

[0039] Cooling towers used in these types of locations are equipped with water-powered fans that use sprayed water to drive the fans to cool the environment.

[0040] In the process of cooling the environment, the spray water in existing cooling towers comes into contact with the outside air. The spray water often adsorbs and dissolves a large amount of dust and impurities, resulting in serious pollution of the spray water. This leads to an excessive amount of impurities in the spray water. When the spray water drives the hydraulic fan to rotate, the impurities in the spray water will come into contact with and adhere to the functional components of the hydraulic fan, causing the hydraulic fan to slow down or even jam, affecting the rotation of the hydraulic fan, reducing the working efficiency of the hydraulic fan, and thus reducing the overall cooling efficiency of the cooling tower. At the same time, it also affects the service life of the hydraulic fan.

[0041] Based on the above background, see Figure 1 This application provides an air conditioning system, which includes a heat exchanger 100, a hydraulic fan 200, and a first coolant supply device 300.

[0042] The heat exchanger 100 is used to circulate a first coolant. A hydraulic fan 200 is used to introduce air into the heat exchanger 100 so that the air exchanges heat with the first coolant in the heat exchanger 100, and then discharges the heated air. A first coolant supply device 300 is configured to supply the first coolant to the inlet of the hydraulic fan 200 to drive the hydraulic fan 200 to rotate. Furthermore, the first coolant flowing out of the outlet of the hydraulic fan 200 is introduced into the heat exchanger 100.

[0043] It should be noted that, in Figure 1 In the diagram, the dashed arrow indicates the flow direction of the first coolant.

[0044] The heat exchanger 100 is preferably a coil-type heat exchanger, thereby increasing the heat exchange area between the air and the first coolant flowing in the heat exchanger 100 and accelerating the cooling rate of the air in the environment.

[0045] The hydraulic fan 200 is a hydraulic fan structure in the prior art, that is, the hydraulic fan 200 includes a turbine and fan blades arranged coaxially, and the turbine is provided with a liquid inlet and a liquid outlet, which are the liquid inlet and liquid outlet of the hydraulic fan 200.

[0046] It should be noted that when the first coolant supply device 300 inputs the first coolant into the inlet of the hydraulic fan 200 to drive the hydraulic fan 200 to rotate, the first coolant input by the first coolant supply device 300 into the inlet of the hydraulic fan 200 has considerable kinetic energy. The first coolant does work on the turbine of the hydraulic fan 200, thereby driving the turbine of the hydraulic fan 200 to rotate, which in turn drives the fan blades to rotate, thereby drawing the relatively hot air in the mine environment to the location of the heat exchanger 100. The air comes into contact with the pipes of the heat exchanger 100 and exchanges heat with the first coolant in the pipes of the heat exchanger 100. The first coolant in the heat exchanger 100 absorbs heat from the air, thereby cooling the air. After the first coolant has done work on the hydraulic fan 200, it flows from the outlet of the hydraulic fan 200 into the pipes of the heat exchanger 100, providing the heat exchanger 100 with a fluid medium for heat exchange with the air.

[0047] Furthermore, it should be noted that the inlet of the first coolant supply device 300 and the hydraulic fan 200, as well as the outlet of the hydraulic fan 200 and the heat exchanger 100, are all connected by pipelines. The first coolant can be pre-prepared clean cooling water to ensure its cleanliness.

[0048] In addition, the first coolant supply device 300 can also be connected to external refrigeration or air conditioning equipment, so that the external refrigeration or air conditioning equipment can continuously supply the first coolant supply device 300 with a lower temperature, ensuring that the hydraulic fan 200 can be continuously driven to rotate. Moreover, in order to increase the kinetic energy of the first coolant input to the hydraulic fan 200, a corresponding power water pump can be configured on the first coolant supply device 300 to give the first coolant input to the hydraulic fan 200 greater kinetic energy and increase the rotation speed of the hydraulic fan 200.

[0049] In other embodiments, the two ends of the heat exchanger 100 are the inlet and outlet of the heat exchanger 100, respectively. The outlet of the heat exchanger 100 can be connected to an external first coolant recovery device to recover the first coolant that has undergone heat exchange in the heat exchanger 100. Since the first coolant in the heat exchanger 100 absorbs heat from the air, the temperature of the first coolant flowing out of the outlet of the heat exchanger 100 increases. After the first coolant recovery device recovers the corresponding first coolant, it can also introduce the first coolant into the corresponding refrigeration equipment or air conditioning equipment to cool down the recovered first coolant. Then, the first coolant with a lower temperature is introduced into the first coolant supply device 300, thereby realizing the recycling of the first coolant.

[0050] Of course, in other embodiments, the outlet of the heat exchanger 100 can be directly connected to the first coolant supply device 300 through a pipeline, so that the first coolant that has undergone heat exchange can be directly recovered into the first coolant supply device 300. The recovered first coolant is directly mixed with the original first coolant in the first coolant supply device 300, which can also achieve the cooling effect of the recovered first coolant and realize the recycling of the first coolant.

[0051] It is easy to understand that the air conditioning system of this application introduces a first coolant into the inlet of the hydraulic fan 200 by setting a first coolant supply device 300. The kinetic energy of the first coolant drives the hydraulic fan 200 to rotate, so as to introduce the air with a higher ambient temperature into the heat exchanger 100, so that the air exchanges heat with the first coolant flowing in the pipes of the heat exchanger 100. The first coolant in the heat exchanger 100 absorbs the heat in the air, thereby cooling the air.

[0052] Meanwhile, by introducing the first coolant flowing out of the outlet of the hydraulic fan 200 into the heat exchanger 100, the first coolant that has completed its work on the hydraulic fan 200 can flow from the outlet of the hydraulic fan 200 into the heat exchanger 100, continuously providing the heat exchanger 100 with the first coolant for heat exchange with the air. In this way, the first coolant supply device 300, the hydraulic fan 200 and the heat exchanger 100 form an air conditioning system that can cool and lower the temperature of the environment.

[0053] When the cooling tower is equipped with this air conditioning system, the heat exchanger 100 and the hydraulic fan 200 are both installed in the tower body of the cooling tower, and the hydraulic fan 200 is located above the heat exchanger 100. When the hydraulic fan 200 rotates, it draws the hotter air at the bottom of the tower from bottom to top, so that the air is cooled down by the heat exchanger 100 and discharged into the atmosphere from the air outlet of the hydraulic fan 200.

[0054] When the cooling tower with this air conditioning system cools the mine environment, the first coolant supply device 300 can directly and continuously supply clean first coolant to the hydraulic fan 200, so that the clean first coolant drives the hydraulic fan 200 to rotate continuously, replacing the traditional method of driving the hydraulic fan 200 with cooling water that is polluted by the mine environment. This avoids dust and other impurities in the mine from entering the hydraulic fan 200 and affecting its working efficiency, ensuring the overall cooling efficiency of the cooling tower for the mine, and also making the hydraulic fan 200 easy to maintain.

[0055] Meanwhile, the first coolant output from the first coolant supply device 300 can be recovered into the heat exchanger 100, thereby continuously providing the heat exchanger 100 with the first coolant for heat exchange with the air in the mine. In this process, the first coolant is also prevented from being contaminated by direct contact with the air in the mine. This not only ensures the quality of the first coolant but also realizes the recycling of the first coolant, improving the utilization efficiency of the first coolant.

[0056] In some embodiments of this application, see Figure 1 The first coolant supply device 300 is connected to the liquid inlet of the hydraulic fan 200 through the first pipeline 400, and the first pipeline 400 is equipped with a first flow regulating valve 410.

[0057] Specifically, the first flow regulating valve 410 is preferably a manual regulating valve, which is suitable for the mine environment where there is no electricity, and also facilitates the operation of the first flow regulating valve 410 by the operators in the mine.

[0058] This application provides a first flow regulating valve 410 in the first pipeline 400. By adjusting the opening of the first flow regulating valve 410, the flow rate and kinetic energy of the first coolant input to the inlet of the hydraulic fan 200 can be adjusted, thereby increasing or decreasing the speed of the hydraulic fan 200 to meet the diverse cooling and temperature reduction needs of the on-site environment, while also meeting energy-saving requirements.

[0059] In some embodiments of this application, see Figure 1 and Figure 2 The first coolant supply device 300 is also connected to the inlet of the heat exchanger 100 through the second pipeline 500 to supply the first coolant to the heat exchanger 100.

[0060] Similarly, in Figure 1 and Figure 2 In the middle, the dashed arrow indicates the flow direction of the first coolant on the surface.

[0061] This application connects the first coolant supply device 300 to the inlet of the heat exchanger 100 through the second pipeline 500, so that the first coolant supply device 300 can input the first coolant into the heat exchanger 100 through the second pipeline 500, thereby increasing the flow rate of the first coolant flowing in the pipeline of the heat exchanger 100, improving the heat exchange efficiency between the air in the mine and the first coolant, and thus accelerating the cooling of the mine environment.

[0062] See also some embodiments of this application. Figure 1 and Figure 2 A second flow regulating valve 510 is installed on the second pipeline 500.

[0063] Specifically, the second flow regulating valve 510 is a manual regulating valve, which is adapted to the mine environment where there is no electricity, and also facilitates the operation of the second flow regulating valve 510 by the operators in the mine.

[0064] It is easy to understand that by setting a second flow regulating valve 510 in the second pipeline 500, the flow rate of the first coolant entering the heat exchanger 100 can be adjusted by adjusting the opening of the second flow regulating valve 510, so as to meet the diverse needs of cooling and temperature reduction of the on-site environment, and at the same time meet the energy-saving requirements.

[0065] See also some embodiments of this application. Figure 2 The outlet of the hydraulic fan 200 is connected to the second pipe 500 through the third pipe 600, so that the first coolant flowing out of the outlet of the hydraulic fan 200 is introduced into the heat exchanger 100 through the second pipe 500.

[0066] Specifically, a T-junction can be installed between the third pipe 600 and the second pipe 500 to facilitate the connection between the third pipe 600, the second pipe 500 and the liquid inlet of the heat exchanger 100.

[0067] Understandably, the above configuration allows the heat exchanger 100 to have two flow paths for supplying the first coolant: one is the first coolant flowing out of the outlet of the hydraulic fan 200, and the other is the first coolant directly input into the heat exchanger 100 by the first coolant supply device 300. This increases the flow rate of the first coolant circulating in the heat exchanger 100, further improving the heat exchange efficiency between the air and the first coolant in the mine, thereby accelerating the cooling and temperature reduction of the mine environment.

[0068] Moreover, the first coolant in both flow paths does not come into direct contact with the external environment, preventing the first coolant from seeping into the environment and causing dust and other impurities to affect the rotation of the hydraulic fan 200. This allows the first coolant to maintain its initial cleanliness, ensuring the overall cooling efficiency of the cooling tower for the mine, and also making the hydraulic fan 200 easy to maintain.

[0069] See also some embodiments of this application. Figure 1 and Figure 2 The outlet of heat exchanger 100 is connected to the first coolant supply device 300.

[0070] Specifically, the heat exchanger 100 is a coil heat exchanger. The outlet of the heat exchanger 100 can be directly connected to the first coolant supply device 300 through a pipeline, so that the first coolant that has undergone heat exchange can be directly recovered into the first coolant supply device 300. The recovered first coolant is directly mixed with the original first coolant in the first coolant supply device 300, which can achieve the cooling effect of the recovered first coolant and realize the recycling of the first coolant.

[0071] In some embodiments of this application, see Figure 3 This application also provides a cooling tower 10, which includes the above-described air conditioning system.

[0072] It should be noted that, in Figure 3 In the diagram, the dashed arrow indicates the direction of the first coolant flow.

[0073] The cooling tower 10 of this application, having the aforementioned air conditioning system, also possesses the same technical effects as such an air conditioning system. Specifically, when cooling the mine environment, the cooling tower 10 prevents dust and other impurities from entering the hydraulic fan 200 and affecting its operating efficiency, thus ensuring the overall cooling efficiency of the cooling tower. Simultaneously, it prevents the first coolant from directly contacting and contaminating the air inside the mine, ensuring the quality of the first coolant and enabling its recycling, thereby improving its utilization efficiency.

[0074] See also some embodiments of this application. Figure 3 The cooling tower 10 also includes a sprayer 700, which is configured to spray a second coolant onto the heat exchanger 100.

[0075] Specifically, when the cooling tower 10 of this application is applied in a mining environment, the heat exchanger 100, the hydraulic fan 200, and the sprayer 700 are all installed in the tower body of the cooling tower, and the heat exchanger 100, the sprayer 700, and the hydraulic fan 200 are arranged sequentially from bottom to top along the tower body of the cooling tower at intervals, that is, the sprayer 700 is located between the hydraulic fan 200 and the heat exchanger 100. The second coolant sprayed by the sprayer 700 can be cooling water.

[0076] The sprayer 700 may include multiple nozzles, which spray a second coolant onto the surface of the pipes of the heat exchanger 100. The second coolant forms a water film on the surface of the pipes of the heat exchanger 100, and the evaporation carries away the heat inside the pipes of the heat exchanger 100 to cool the first coolant in the heat exchanger 100. At the same time, as the multiple nozzles spray the second coolant vertically downward, the air at the bottom of the tower is drawn out from bottom to top by the hydraulic fan 200. In this way, the second coolant can also directly exchange heat with the air in the environment.

[0077] The second coolant sprayed downwards by the sprayer 700 can exchange heat with the first coolant flowing in the pipes of the heat exchanger 100. Since the first coolant in the pipes of the heat exchanger 100 has absorbed some of the heat in the mine environment, its temperature is higher than that of the second coolant. Thus, the second coolant sprayed downwards by the sprayer 700 can directly cool the heat exchanger 100, so that the first coolant in the heat exchanger can be recovered into the first coolant supply device 300 without a significant temperature increase. In this way, a closed first coolant circulation path is formed between the first coolant supply device 300, the hydraulic fan 200, and the heat exchanger 100, and most of the heat in the mine environment is absorbed by the second coolant.

[0078] On the other hand, the second coolant sprayed downwards by the sprayer 700 can work together with the first coolant in the heat exchanger 100 to cool the air in the mine environment, thus accelerating the cooling rate of the mine environment.

[0079] Of course, operators can also selectively turn the sprinkler 700 on or off according to the actual temperature requirements of the mine environment to meet the usage needs.

[0080] See also some embodiments of this application. Figure 3 The cooling tower 10 also includes a second coolant supply device 800, which is configured to recover the second coolant that has fallen off the heat exchanger 100 and to supply the second coolant to the sprayer 700.

[0081] Specifically, the second coolant supply device 800 can be a water tank with an opening at the top. It should be noted that after the sprayer 700 sprays the second coolant onto the surface of the heat exchanger 100, the second coolant passes over the surface of the heat exchanger 100 and exchanges heat with the first coolant flowing inside the heat exchanger 100. Some unevaporated droplets of the second coolant will slide off the surface of the pipes of the heat exchanger 100. Through the arrangement of the second coolant supply device 800, the second coolant supply device 800 can receive the second coolant that slides off the heat exchanger 100, thus completing the recycling of the second coolant.

[0082] At the same time, a second coolant is introduced into the sprayer 700 through the second coolant supply device 800, which also serves to supply a second coolant to the sprayer 700.

[0083] See also some embodiments of this application. Figure 3 The second coolant supply device 800 is connected to the sprayer 700 through the fourth pipeline 900, and the fourth pipeline 900 is equipped with a third flow regulating valve 910.

[0084] Specifically, the third flow regulating valve 910 is a manual regulating valve, which is adapted to the mine environment where there is no electricity, and also facilitates the operation of the third flow regulating valve 910 by the operators in the mine.

[0085] It is easy to understand that by setting a third flow regulating valve 910 in the fourth pipeline 900, the flow rate of the second coolant entering the sprayer 700 can be adjusted by adjusting the opening of the third flow regulating valve 910, which effectively improves the utilization rate of the second coolant and can also control the density of the second coolant sprayed into the heat exchanger 100. This allows it to adapt to the required second coolant density and flow rate under different working conditions and meet the diverse needs of cooling and temperature reduction of the on-site environment.

[0086] See also some embodiments of this application. Figure 3 The fourth pipeline 900 is also equipped with a water pump 920, which is a power water pump that can draw the second coolant in the second coolant supply equipment 800 at the bottom of the tower to the sprayer 700. It can also increase the kinetic energy of the second coolant as needed, increase the density of the second coolant sprayed by the sprayer 700, and improve the cooling efficiency of the mine environment.

[0087] Additionally, see also some embodiments of this application. Figure 3The cooling tower 10 also includes a ventilation packing structure 11, which is specifically a finned structure. The ventilation packing structure 11 is disposed between the heat exchanger 100 and the second coolant supply device 800, and is spaced apart from both the heat exchanger 100 and the second coolant supply device 800.

[0088] As the second coolant sprayed by the sprayer 700 slides down the heat exchanger 100, it first falls onto the ventilation packing structure 11 and flows within it. When the hydraulic fan 200 rotates, the air flows from bottom to top and also passes through the ventilation packing structure 11. Thus, the relative flow of the second coolant within the ventilation packing structure 11 causes the second coolant to evaporate and carry away heat from the air, thereby further improving the cooling efficiency of the cooling tower 10.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and they should all be covered within the scope of the claims and specification of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
